ASPECIFICATION forming part of Letters Patent No. 258,039, dated May 16,1882. Application ileddanuary 16, 1882. (No model.)

To all whom 'it may concern Be it known that I, NVM. L. EVERIT, o NewHaven, in the county of New Haven and State ot' Connecticut,haveinventeda new Improvement in Gar-Couplings, and I do hereby declare thefollowing, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1,a side view; Fig.2, a longitudinal central section Fig. 3, avertical section cutting in front ot' the locking-lever; Fig. 4, atransversesection through t-headjusting-screw.

This invention relates to an improvement in the car-coupling for whichLetters Patent ot' the United States were granted to me dated October 5,1880,'N0. 232,953. In that patent the lever which locks the bolt afterthe link has been introduced was hinged upon one side ot' lthe head,extended across in front of the bolt to the opposite side, where it washung to a latching-lever, so that when the latch was disengaged it wouldraise that end of the lever and bring it up iu front ofthe bolt. Thisgave to the locking-lever a vibratory movement, it turning on a pivot orfulcruin at one end, and necessitates a bolt to make that pivot. InpracticeI find such bolts or hinged connections to be objectionable. I

The object of my present invention is principally to overcomethisobjection and raise theV lever or bar bodily upward, instead of avibratorymovement; anditconsistsin arranging the bar upon inclinedseats, and so that when the latching-lever is disengaged` it will drawthe locking-bar toward that side and up the inclines, raising it bodilyin front ot" the bolt; and it also consists in adevicefor adjusting thecoupler so as to engage cars of widely-` Thus, unless preveuteththe boltwill be turned forward by drawing upon .the link unt-il the link willescape from the bolt, as indicated in broken lines, Fig. 2.

Below the mouth B, and forward of the bolt, the transverse locking-bar Fis arranged. This bar, instead of being hinged at one side, as in myprevious patent, is constructed upon its under side with two inclines, bb, and the seat in which it rests in vits normal condition, as

seen in Fig. 3, is constructed with two corresponding inclines orshoulders, d. The bar extends across to the opposite side, where itishung to the lower end of the latch-lever G. The said latch-lever G isarranged to swing upon a pivot, c. It is engaged with the bar F by astud,f, on the latch-lever working ina slot, h, in the end of the bar.The latch-lever G is engaged at the upper end by a latch, H, hingeduponthe opposite side, as at t', so as to engage a shoulder, Z, on thelatch-lever' when the said latch-lever is turned into its uprightposition, as seen in Fig. 3. In this condition the bar F lies below thebolt D, and so that the bolt will swing free of it to permit thelink tobe drawn out. The stud f' on the lever Gr is eccentric to the pivot c orcenter of motion on which it turns. Hence when the lever Gris dropped,as indicated in broken lines, Fig. 3, it turns and draws the bar Ftoward it. The bar riding up the inclines rises bodily upward, and so asto bring it in front of the bolt, as seen in broken lines, Figs. 2 and3.

The upper end of the bolt D is made camshaped, as at f, so that when thelink E is forced inward and turns the bolt, as seen in Fig. 2, thecam-shaped end of the'bolt strikes the latch H and lifts it, asindicated in broken lines, Fig. 3. In thus rising, the back of thelatch, as its nose passes from the shoulder l, strikes an incline, m,onthe lever G above and forces it away until it has passed its center ofgravity. Then theleverGrfalls ofitsown weight and raises the bar F, asbefore described, into its position in front of the bolt, and thus holdsthe bolt within the link and prevents the link from beingdrawn out. Whenit is desired to disengage the link the lever G is turned up, the latchH automatically engaging with it, as

` seen in Fig. 3, which causes the bar F to fall down the inclines andrelease the bolt, as before described.

IOO

2 sesame vThis is usually done by means ot' bent links,

which occasion little inconvenience it' they happen to be at hand, butthey are seldom so readily to be found.

To adjust the coupler to different elevations I arrange a yoke, L,across beneath the body of the coupler, and through that is anadjusting-screw, l), upon which the coupler will rest.

.Then by turning the screw in one direction or the other the coupler maybe raised or lowered accordingly, and thus the coupler is readilyadapted to other couplers of ditt'erent elevations Without the changeot' links.

What I claim as an improvement on my Patent No. 232,953 is- 1. Thecombination of the bolt D, the latching-lever G, and its latch H withthe bar F, arranged transversely across in front of and below the bolt,constructed with inclined seats below and engaged with the saidlatch-lever Gr, so that asthe said latch-lever Gr is turned in onedirection it will dra-W the bar towardit and up the inclines to raisethe bar bodily, and in the opposite direction permit the bar to falldown the inclines, substantially as described.

2. In acar-eoupling, the yoke L and adjusting-screw P, for theadjustment of the elevation ot' the coupler, substantially as described.
